Respiratory failure & ventilation
Feasibility study of the use of a wearable vital sign patch in an intensive care unit setting
Authors' conclusion
A very high correlation was found between the heart rate measured by the Vivalink Cardiac patch and that of the ECG-based monitoring system of the hospital. Concerning respiratory rate the correlation between the data from the Vivalink Cardiac patch, the ECG-based monitoring system and the ventilation machine was found to be moderate.
Study context

Main finding
As reported in the abstract
Heart rate: time within 5% error range of ECG-based monitoring (mean±SD, % of measured time)
85.11±10.81%
Respiratory rate: time within 5% error range of ECG-based monitoring (mean±SD, % of measured time)
40.55±17.28%
Heart rate: Spearman correlation, very high
ρ = 0.9 8
Respiratory rate: Spearman correlation, moderate
ρ = 0.66
Observational data: associations, not effects.
Further findings
Respiratory rate vs ventilation machine (ventilated patients)
- Vivalink and ECG-based monitoring both moderately correlated with ventilated respiratory rate
- ρ = 0.68
